Been measuring to get an idea where the build will go and hit a minor bump. It's a '31 coupe (body and frame), full-fendered that'll run bigs and littles with front discs. The front will get a 4" drop I-beam axle, but I've seen 46 & 48" width axles available. Fenderless it wouldn't be as big of an issue, but I don't want the tires too far outboard in the fenders. I haven't seen much difference in backspacing on 15x6 wheels and I know that will be a factor (as well as the discs to an extent), but which width axle seems to fit best on full fendered A's?
